sorry to all offended
when a parent want to send a bachor to learn in E.Y i dont think they are interested in him making money to support himself. and if parents cant afford to send them there are people these days who dont go to E.Y.
and yes there are always people in yeshivas binding giving haircuts i did them my self but thats in yeshiva not out of yeshiva!
and yes if he wants to go work (and learn)nothing wrong either
